Thanks

similar name (like coin space).
If that was 2015 or 2016 then it was definitely us, since back then there were very few non-custodial/self-custodial wallets on the market, and yes, our domain is
https://coin.space/Not everything, in fact.
There's no hardware and multisig support. It looks like there's no support for connecting to your own Bitcoin node not to mention both CBF and SP buzz.
We feel this is a very niche use case that maybe 0.1% of users would actually need. If there's real data on this- please share it, and we're happy to discuss further.
An 11-year absence is evident.
But perhaps someone would be interested in such minimalistic wallet. Who knows.
In 2015 it started as a web app, then we built for android and iOS, then desktop for windows and Linux, TOR, and of course added more currencies.
We are strongly in favor of minimalism in wallet: no damn token news, no junk notifications. Open it, send bitcoin, close it and forget about it.
